Studdy Solution

STEP 1

What is this asking? Which division problem gives us 61? Watch out! Don't rush!
It's easy to make small mistakes with long division, so take your time and double-check your work.

STEP 2

1. Divide 2914 by 47
2. Divide 4650 by 75
3. Divide 3276 by 52
4. Divide 5063 by 83

STEP 3

Let's **divide** 29142914 by 4747.
We're doing this because the problem asks us to find which expression has a quotient of 6161.

STEP 4

We ask ourselves, how many times does 4747 go into 291291?
It goes in 66 times, because 647=2826 \cdot 47 = 282.
Subtracting 282282 from 291291 leaves us with 99.
Bringing down the next digit, 44, gives us 9494.

STEP 5

How many times does 4747 go into 9494?
It goes in 22 times, because 247=942 \cdot 47 = 94.
Subtracting 9494 from 9494 leaves us with 00.

STEP 6

So, 2914÷47=622914 \div 47 = 62.
This isn't **61**, so this isn't the answer we're looking for!

STEP 7

Now let's **divide** 46504650 by 7575.
Remember, we're looking for a quotient of 6161.

STEP 8

How many times does 7575 go into 465465?
It goes in 66 times, because 675=4506 \cdot 75 = 450.
Subtracting 450450 from 465465 leaves us with 1515.
Bringing down the 00 gives us 150150.

STEP 9

How many times does 7575 go into 150150?
It goes in 22 times, because 275=1502 \cdot 75 = 150.
Subtracting 150150 from 150150 leaves us with 00.

STEP 10

So, 4650÷75=624650 \div 75 = 62.
Still not **61**!
Let's keep going!

STEP 11

Let's **divide** 32763276 by 5252.
We're getting closer to finding that **61**!

STEP 12

5252 goes into 327327 six times, because 652=3126 \cdot 52 = 312.
Subtracting 312312 from 327327 leaves us with 1515.
Bringing down the 66 gives us 156156.

STEP 13

5252 goes into 156156 three times, because 352=1563 \cdot 52 = 156.
Subtracting 156156 from 156156 leaves us with 00.

STEP 14

So, 3276÷52=633276 \div 52 = 63.
So close!
But still not **61**.
Onwards!

STEP 15

Finally, let's **divide** 50635063 by 8383.
This is the last one, so fingers crossed we find our **61**!

STEP 16

8383 goes into 506506 six times, because 683=4986 \cdot 83 = 498.
Subtracting 498498 from 506506 leaves us with 88.
Bringing down the 33 gives us 8383.

STEP 17

8383 goes into 8383 one time, because 183=831 \cdot 83 = 83.
Subtracting 8383 from 8383 leaves us with 00.

STEP 18

So, 5063÷83=615063 \div 83 = 61.
We found it!

STEP 19

5063÷835063 \div 83 has a quotient of 61.
